Phenyl-substituted 2-enamino-ketonitriles

ABSTRACT

The present invention relates to novel phenyl-substituted 2-enamino-ketonitriles of the formula (I): 
                         
in which
     Ar, X, Z, Y and K are each as defined in the description,
 
to a plurality of processes for their preparation and to their use as herbicides and pesticides.

The invention relates to novel phenyl-substituted 2-enamino-ketonitriles, to a plurality of processes for their preparation and to their use as crop protection agents, in particular as herbicides, acaricides, nematicides and insecticides

Certain 2-enamino-ketonitriles which are substituted on the phenyl ring and have herbicidal action have already been disclosed, for example in EP-A 0 348 002. However, these 2-[3-phenoxy- or 3-[(2-pyridyloxy)benzoyl]-3-(dialkylamino)acrylonitriles have hitherto not attained any importance.

Likewise without any significant importance are the compounds with herbicidal properties disclosed in JP-A2 10 175 937, WO 99/16753 and EP-A 0 490 220.

Furthermore, 2-enamino-ketonitriles have been disclosed for use as intermediates for the synthesis of antibacterial active compounds, see DE-A 35 02 935, EP-A 0 220 523, DE 34 26 483 and EP-A 0 168 737.

Further 2-enamino-ketonitriles are also known from DE-A 19 958 164, DE-A 19 851 986, DE-A 10 007 286 and WO 00/27812.

Also known are 2-enamino-ketonitriles which are unsubstituted on the phenyl ring (I. N. Sobhy, H. S. Zahi, M. M. Hassan, E. M. Hilmy, (Chem. Ind. (London), 1988, 17, 563–564), I. N. Sobhy, M. M.

Crop plants can be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or combinations of these methods, including the transgenic plants and including plant cultivars which can or cannot be protected by plant breeders' certificates. Parts of plants are to be understood as meaning all above-ground and below-ground parts and organs of plants, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stems, trunks, flowers, fruit-bodies, fruits and seeds and also roots, tubers and rhizomes.

By controlling these arthropods, cases of death and reduction in productivity (for meat, milk, wool, hides, eggs, honey etc.) should be diminished, so that more economic and easier animal husbandry is possible by use of the active compounds according to the invention.

The active compounds according to the invention are used in the veterinary sector in a known manner by enteral administration in the form of, for example, tablets, capsules, potions, drenches, granules, pastes, boluses, the feed-through process and suppositories, by parenteral administration, such as, for example, by injection (intramuscular, subcutaneous, intravenous, intraperitoneal and the like), implants, by nasal administration, by dermal use in the form, for example, of dipping or bathing, spraying, pouring on and spotting on, washing and powdering, and also with the aid of molded articles containing the active compound, such as collars, ear marks, tail marks, limb bands, halters, marking devices and the like.

When used for cattle, poultry, pets and the like, the active compounds of the formula (I) can be used as formulations (for example powders, emulsions, free-flowing compositions), which comprise the active compounds in an amount of 1 to 80% by weight, directly or after 100- to 10 000-fold dilution, or they can be used as a chemical bath.

It has furthermore been found that the compounds of the formula (I) according to the invention also have a strong insecticidal action against insects which destroy industrial materials.

The following insects may be mentioned as examples and as preferred—but without a limitation:

-   Beetles, such as Hylotrupes bajulus, Chlorophorus pilosis, Anobium     punctatum, Xestobium rufovillosum, Ptilinus pecticornis, Dendrobium     pertinex, Emobius mollis, Priobium carpini, Lyctus brunneus, Lyctus     africanus, Lyctus planicollis, Lyctus linearis, Lyctus pubescens,     Trogoxylon aequale, Minthes rugicollis, Xyleborus spec.,     Tryptodendron spec., Apate monachus, Bostrychus capucins,     Heterobostrychus brunneus, Sinoxylon spec. and Dinoderus minutus. -   Hymenopterons, such as Sirex juvencus, Urocerus gigas, Urocerus     gigas taignus and Urocerus augur. -   Termites, such as Kalotermes flavicollis, Cryptotermes brevis,     Heterotermes indicola, Reticulitermes flavipes, Reticulitermes     santonensis, Reticulitermes lucifugus, Mastotermes darwiniensis,     Zootermopsis nevadensis and Coptotermes formosanus. -   Bristletails, such as Lepisma saccarina.

Industrial materials in the present connection are to be understood as meaning non-living materials, such as, preferably, plastics, adhesives, sizes, papers and cardboards, leather, wood and processed wood products and coating compositions.

Wood and processed wood products are materials to be protected, especially preferably, from insect infestation.

Wood and processed wood products which can be protected by the agents according to the invention or mixtures comprising these are to be understood as meaning, for example: building timber, wooden beams, railway sleepers, bridge components, boat jetties, wooden vehicles, boxes, pallets, containers, telegraph poles, wood panelling, wooden windows and doors, plywood, chipboard, joinery or wooden products which are used quite generally in house-building or in building joinery.

The active compounds can be used as such, in the form of concentrates or in generally customary formulations, such as powders, granules, solutions, suspensions, emulsions or pastes.

The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds with at least one solvent or diluent, emulsifier, dispersing agent and/or binder or fixing agent, a water repellent, if appropriate siccatives and UV stabilizers and if appropriate dyestuffs and pigments, and also other processing auxiliaries.

The insecticidal compositions or concentrates used for the protection of wood and timber products comprise the active compound according to the invention in a concentration of 0.0001 to 95% by weight, in particular 0.001 to 60% by weight.

The amount of the compositions or concentrates employed depends on the nature and occurrence of the insects and on the medium. The optimum amount employed can be determined for the use in each case by a series of tests. In general, however, it is sufficient to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of the active compound, based on the material to be protected.

Solvents and/or diluents which are used are an organochemical solvent or solvent mixture and/or an oily or oil-like organochemical solvent or solvent mixture of low volatility and/or a polar organochemical solvent or solvent mixture and/or water, and if appropriate an emulsifier and/or wetting agent.

Organochemical solvents which are preferably used are oily or oil-like solvents having an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C. Substances which are used as such oily or oil-like water-insoluble solvents of low volatility are appropriate mineral oils or aromatic fractions thereof, or solvent mixtures containing mineral oils, preferably white spirit, petroleum and/or alkylbenzene.

Mineral oils having a boiling range from 170 to 220° C., white spirit having a boiling range from 170 to 220° C., spindle oil having a boiling range from 250 to 350° C., petroleum and aromatics having a boiling range from 160 to 280° C., turpentine oil and the like, are advantageously employed.

In a preferred embodiment, liquid aliphatic hydrocarbons having a boiling range from 180 to 210° C. or high-boiling mixtures of aromatic and aliphatic hydrocarbons having a boiling range from 180 to 220° C. and/or spindle oil and/or monochloronaphthalene, preferably α-monochloronaphthalene, are used.

The organic oily or oil-like solvents of low volatility which have an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C., can be replaced in part by organochemical solvents of high or medium volatility, providing that the solvent mixture likewise has an evaporation number above 35 and a flashpoint above 30° C., preferably above 45° C., and that the insecticide/fungicide mixture is soluble or emulsifiable in this solvent mixture.

According to a preferred embodiment, some of the organochemical solvent or solvent mixture is replaced by an aliphatic polar organochemical solvent or solvent mixture. Aliphatic organochemical solvents containing hydroxyl and/or ester and/or ether groups, such as, for example, glycol ethers, esters or the like, are preferably used.

Organochemical binders which are used in the context of the present invention are the synthetic resins and/or binding drying oils which are known per se, are water-dilutable and/or are soluble or dispersible or emulsifiable in the organochemical solvents employed, in particular binders consisting of or comprising an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenolic resin, hydrocarbon resin, such as indene-cumarone resin, silicone resin, drying vegetable oils and/or drying oils and/or physically drying binders based on a natural and/or synthetic resin.

The synthetic resin used as the binder can be employed in the form of an emulsion, dispersion or solution. Bitumen or bituminous substances can also be used as binders in an amount of up to 10% by weight. Dyestuffs, pigments, water-repelling agents, odour correctants and inhibitors or anticorrosive agents and the like which are known per se can additionally be employed.

It is preferred according to the invention for the composition or concentrate to comprise, as the organochemical binder, at least one alkyd resin or modified alkyd resin and/or one drying vegetable oil. Alkyd resins having an oil content of more than 45% by weight, preferably 50 to 68% by weight, are preferably used according to the invention.

All or some of the binder mentioned can be replaced by a fixing agent (mixture) or a plasticizer (mixture). These additives are intended to prevent evaporation of the active compounds and crystallization or precipitation. They preferably replace 0.01 to 30% of the binder (based on 100% of the binder employed).

The plasticizers originate from the chemical classes of phthalic acid esters, such as dibutyl, dioctyl or benzyl butyl phthalate, phosphoric acid esters, such as tributyl phosphate, adipic acid esters, such as di-(2-ethylhexyl) adipate, stearates, such as butyl stearate or amyl stearate, oleates, such as butyl oleate, glycerol ethers or higher molecular weight glycol ethers, glycerol esters and p-toluenesulphonic acid esters.

Fixing agents are based chemically on polyvinyl alkyl ethers, such as, for example, polyvinyl methyl ether or ketones, such as benzophenone or ethylenebenzophenone.

Possible solvents or diluents are, in particular, also water, if appropriate as a mixture with one or more of the abovementioned organochemical solvents or diluents, emulsifiers and dispersing agents.

Particularly effective preservation of wood is achieved by impregnation processes on a large industrial scale, for example vacuum, double vacuum or pressure processes.

The ready-to-use compositions can also comprise other insecticides, if appropriate, and also one or more fungicides, if appropriate.

Possible additional mixing components are, preferably, the insecticides and fungicides mentioned in WO 94/29 268. The compounds mentioned in this document are an explicit constituent of the present application.

Especially preferred mixing partners which may be mentioned are insecticides, such as chlorpyriphos, phoxim, silafluofin, alphamethrin, cyfluthrin, cypermethrin, deltamethrin, permethrin, imidacloprid, NI-25, flufenoxuron, hexaflumuron and triflumuron, and also fungicides, such as epoxyconazole, hexaconazole, azaconazole, propiconazole, tebuconazole, cyproconazole, metconazole, imazalil, dichlorfluanid, tolylfluanid, 3-iodo-2-propinyl-butyl carbamate, N-octyl-isothiazolin-3-one and 4,5-dichloro-N-octylisothiazolin-3-one.

The active compounds according to the invention can be used particularly effectively for controlling plant-damaging insects, such as, for example, against the larvae of the mustard beetle (Phaedon cochleariae), against the larvae of the green rice leafhopper (Nephotettix cincticeps) and against the larvae of the green peach aphid (Myzus persicae).

In addition to the acaricidal, herbicidal and insecticidal properties described, a fungicidal activity of the active compounds according to the invention is noticeable. In both ‘in vitro’ and ‘in vivo’ studies, a broad fungicidal effect can be observed.

Moreover, it was noticed that the active compounds are, in particular, also suitable for controlling mildew, leaf blotch and Fusaria on the infected plants.

The preparation and the use of the active compounds according to the invention is shown in the examples below.
